Abstract
Rhegmatogenous retinal detachment (RRD) is one of the most severe diseases of the visual organ. There is an opinion about the key importance of changes in intraocular hemodynamics on morphofunctional changes in the macular zone in RRD.
Objective: to evaluate changes in the volumetric intraocular blood flow in rhegmatogenous retinal detachment.
Materials and methods. The study included 11 patients (22 eyes) with a diagnosis of primary RRD macula-off up to 30 days old. The main group consisted of eyes with RRD, the control group included paired eyes of the same patients.
Results. In the correlation analysis of the duration of retinal detachment with other studied features, a very high negative correlation was observed with the PA parameter (p = 0.002), a high negative correlation with OFB (p = 0.04) and PV (p = 0.01). No reliable correlation was found with the IOP and PR variables.
Conclusion. As a result of this study, disturbances in the OBF system in patients with primary RRD were established, however, further studies are required to identify and exclude factors contributing to the aggravation of pathological microvascular disturbances in RRD.
